tdf#143081: fix Basic Replace() function crashes LO
0x00007f19c0aa6e57 in rtl::OUStringBuffer::append(char16_t const*, int) (this=0x7fff100d0748, str=0x6f6f46a u"晦饖香©", len=-1) at include/rtl/ustrbuf.hxx:659
0x00007f19c0c3c8a8 in SbRtl_Replace(StarBASIC*, SbxArray&, bool) (rPar=...) at basic/source/runtime/methods.cxx:1321
see bt here:
https://bugs.documentfoundation.org/attachment.cgi?id=173298
Calling xCharClass->toUpper may change words, eg: "Straße" becomes "Strasse"
so the length of the word increases.
In brief, we want to use the length of aSrcStr not aExpStr
